Fluorescent dye that is water-soluble and forms stable thioether bond with free thiol groups. Compared with Cy3 conjugates, those of Fluorescent Dye 555-I Maleimide are slightly red-shifted, resulting in an optimal match to filters designed for Cy3 dyes in accompany with improved photostability. Besides, their fluorescence is pH-independent from pH 3 to 11.

Fluorescent dye that is water-soluble and forms stable Schiff Base with carbonyl group. Compared with Cy3 conjugates, those of Fluorescent Dye 555-I Hydrazide are slightly red-shifted, resulting in an optimal match to filters designed for Cy3 dyes in accompany with improved photostability. Besides, their fluorescence is pH-independent from pH 3 to 11.

Fluorescent dye that is water-soluble and forms stable peptide bond with protein amino groups. Biomolecules conjugated to Fluorescent Dye 594-I Succinimidyl Ester exhibit little spectral overlap with green-fluorescent conjugates, and can be efficiently excited by 568nm line of Ar-Kr laser and by the 594nm line of orange He-Ne laser.

Fluorescent dye that is water-soluble and forms stable peptide bond with protein amino groups.

Fluorescent dye that is water-soluble and forms stable peptide bond with protein amino groups. Fluorescence emission of Fluorescent Dye 633-I Succinimidyl Ester is well separated from that of other commonly used red fluorophores, such as TAMRA, Texas Red, Alexa Fluor 594, Fluorescent Dye 594-I and R-phycoerythrin, making it ideal for multi-color labeling. In comparison with Alexa Fluor 633, the extinction coefficient of Fluorescent Dye 633-I Succinimidyl Ester is much higher (250,000 cm^-1M^-1).
